Again more problems

[JuanTorre]

I'm tired of the app in my phone. Every time I try to download my songs I can't since download stops saying I don't have enough space in my memory (I have a 16GB SD card). I check on settings and "Storage" has disappeared, as always.  Next day all the songs are eliminated "magically". The same problem in my computer , and all of this can't be solucionated by deleting all the app data, because all happens again and again. I don't want to reconsider about stop paying for my music, so plz help me
